Aspartic acid, N,N'-(2-methyl-1,5-pentanediyl)bis-, tetraethyl ester
What is Aspartic acid, N,N'-(2-methyl-1,5-pentanediyl)bis-, tetraethyl ester?
Aspartic acid, N,N'-(2-methyl-1,5-pentanediyl)bis-, tetraethyl ester (CAS 168253-59-6), also marketed as Desmophen 2061 BD, is a polyaspartic ester used as a reactive building block in polyurea and polyurethane coating systems.
Where is Aspartic acid, N,N'-(2-methyl-1,5-pentanediyl)bis-, tetraethyl ester used?
- Protective coatings: fast-cure two-component polyaspartic topcoats for industrial floors, parking decks and concrete surfaces
- Automotive refinish and OEM coatings: high gloss, UV-stable finishes
- Adhesives and sealants: flexible, weather-resistant formulations for construction joints and structural bonding
- Elastomeric systems: controlled reactivity with HDI or IPDI-based isocyanates
- It reacts with isocyanates as a secondary diamine equivalent to control cure speed and film formation.
Good to know: Offers an extended pot life compared to conventional aliphatic polyurea systems. Buyers should confirm active content and equivalent weight with the supplier to ensure compatibility with specific isocyanate indices.
